An outdoor unit includes a casing having a side surface formed with an inlet port; an outdoor fan arranged above the inlet port in the casing and configured to upwardly blow air; and an outdoor heat exchanger arranged so as to face the inlet port. The outdoor fan includes a fan and a bell mouth provided so as to surround the outer periphery of the fan, and an electric component unit positioned at the periphery of the bell mouth is arranged in the casing.

In an outdoor unit, an electric component unit includes an inlet part which communicates with an outlet side of an air blower and through which air on the outlet side flows into the electric component unit, and an outlet part which communicates with an inlet side of the air blower and through which air flows out from the electric component unit.

An outdoor unit of an air conditioning device includes an outdoor unit main body having a square planar shape, a heat exchanger provided along a side surface of this outdoor unit main body, and a fan provided in an upper part of the outdoor unit main body, the fan for blowing out air in the outdoor unit main body upward. An opening portion capable of providing communication between an interior and an exterior of the outdoor unit main body is formed between a one side end portion and an other side end portion of the heat exchanger adjacent to each other, and in at least one of the side end portions positioned in a peripheral edge of the opening portion, a cover member for covering a heat transfer tube protruding from the side end portion is provided.

Disclosed is an improved air feed valve to be attached to an underwater suit, responsive to a water pressure P measured at a selected point A of the underwater suit for permitting air to flow to the inside of the underwater suit at a predetermined flow rate from an associated compressed air cylinder via its primary pressure-reduction valve and tube, thereby keeping the inner air pressure of the underwater suit at a given value. The air feed valve is set for operation so as to feed air at such a flow rate that the inner air pressure of the underwater suit may be kept at a pressure lower than the pressure P-.sub..DELTA. P measured at a position A-X which is closer by a given distance X to the water surface than the selected point A of the underwater suit.

Disclosed is an improved casing for containing cameras, videocameras, flashlights, portable radios and other articles which can be used in scuba diving. It is designed to cause the inner pressure of the casing to vary and balance with the surrounding water pressure. It is guaranteed free from deformation, collapse or water invasion in underwater use without using thick strong wall or frame structure.

A swim fin has a footwear made of flexible material to make walking easier and a support which is made of rigid material to provide rigidity. A fin is pivotally coupled to the support so that it can rotate between a locked swim position and a walk position. The support can either be permanently attached to the footwear, or removably coupled to a fitting which is permanently attached to the footwear. Extension devices can be provided so that the swim position can be unlocked from the user's knee, without the user having to bend. The shape of the fin is designed to eliminate overlapping with the other fin when the user is walking.

Disclosed is a facemask equipped with earplugs which permits wearers to hear clearly sounds underwater or hear others to speak to each other. The earplugs can be easily removed from their ears after finishing scuba diving. Thus, scuba diving will increase fun. As a matter of course, wearers will not suffer from bradyacusia, and they will have no fear of losing the sense of balance by allowing cold water to reach the semicircular canals of the inner ear while swimming underwater.
